'CARBURETOFL SPECIFICATION formingvpart of Letters Patent No. 522,418, dated July 3, 18911.Y Application led September 12,1892. Serial No. 445,721. (No model.)

To wZ Z lwhom; it may concern:

Be 1t known that I, MALVERN W; ILES, of Denver, county of Arapahoe, State v of Colorado, have invented a certain new and useful Apparatusfor Carbureting Air, of which the followmgis atrue and exact description, reference b elng had to the accompanying draw- 1ngs,wh1ch form a part of this specication.

My lnvention relates to apparatus for carburetlngalr and has for its object to provide carburetlng devices which can be used to carburet large'bodies of air, and in which the danger of iire and explosion will be very small. v

My apparatus is especially, though not exclusively, adaptedfor use in connection with metallurgical furnaces, the carbureted air belng introduced vinto the various furnaces where its presence is desiredi The nature of my invention will be best understood as described in connection with the drawings in whichit is illustrated, and in Which- Y i" FFigure 1 is a plan View. of the apparatus;

1g. 1; Fig. 3 a cross-section von. the line 8 4 of Figi, and Fig. 4 a perspective view of a detail of construction. l

A indicates the carburetor chamberlwhich I prefer to construct in the form of a large sheetmetal pipe supported above the ground by` supports B as indicated. The carburetor coke, indicated at D." *This material can be introduced into thel carb uretor chamber in any convenient' way.; f I have indicated at EE man-holes at the top of the chamberA for the introduction ofv the charcoal, and at E I haveindicated in dotted lines doors provided foi` a similar purpose in the sides of the chamber.v y

Situated in the chamber A, and preferably at the bottom thereof, I provide oil chambers F Which are fed with oil from time'to time as may be necessary by any convenient de-y vice, as shown, a pipe FV leading to each chamber F from anoilisupply pipe F3, valves -F2 being provided in pipesF for controlling the admission' of 'oil-'to the oil chambers.

25a cross-sectionon the line`l-2 of Fig..

Openings G extend through the sides of the chamber A, preferably as shown above'the oil chamber F. These openings are closed by a cast iron plate' G', in' each of which plates are secured a group of pipes G2 Opening to the atmosphere at the top of the plate, and with their lower ends immersed in the Oil in chambers F. In order. to preventthe Y charcoal or other absorbent from falling into the oil chamber F, I provide shields arranged so that they will keep the solid matter from falling into the oil chambers, and at thev same time permit the free escape of air from the Oil chamber into the body of the carburetor. Preferably I use for this purposea pipe C Fig. 4 which rests upon the bottom `of the carburetor surrounding the oil cham-Y ber and extendsup` around the group of pipes G2, the walls being perforated so as to permit the free exit of air. The same purpose can bejserved by providing a grating such as is indicated at C, Fig. 2, and which may extend over each oil chamber, and may also be extended partly or entirely along the vwhole length of the carburetor. The perfo-v rated pipe C, however, is preferable because it keeps tle charcoal or other absorbent m'aterial out of contact with the pipes G2, permitting their ready insertion andy removal, and also because the carbureted'air arising froml .theoil chambers is by ,means ofthe perforations in the pipe C more evenly vdistributed through the charcoal iilling.`

I-I H are conduits leading from the carbux retor to the delivery pipe, I 5 any desirednum- `ber of these conduits maybe employed, 'but danger of bein-g choked bythe charcoaljilling of the carburetor by meansof agrating C2 which holds the charcoal'away from that part of the carburetorl chamber jinto which vthe conduits open.

J .I 'indicate Valves by which conduits H can be opened or closed at Will. These Valves are situated between vthe carburetor vand valves L L'arranged to permit the entrance" I prefer in all cases 'to useA at least two. As

shown these conduitsare protected froingthev of airthroughpipes K to conduitsH vat will; j

and'these valves, as Well as the valves J, are situated between the carburetor and blowers M M which are so arranged that when in operation they will suck their supply either through the carburetor or through the valves L when open, and force it into the delivery pipe I as shown.

M indicates the pulley wheels by which the blowers are driven; N N indicating belts connecting the pulleys M with pulleys O on a `power shaft O.

P P indicate valves by which the conduits H can be opened or closed between the blowers and the delivery pipe.

In cold weather, or when using very heavy oils, it is advisable at times to heat the oil in the oil chambers; for this purpose I lead a pipe Q, from a convenient point in the delivery pipe, and from the pipe Q I lead burner pipes Q' beneath each oil chamber F provided with valves Q2 by which the gas can be regulated at will.

The operation of the apparatus above described is as follows: The chambers F being filled with oil and the charcoal filling D impregnated with oil, as by pouring a quantity through the doors E into the carburetor chamber, the blowers are set in operation, the valves J and P being opened and the valves L closed. The action of the blowers suck air down through the pipe groups Gr2 into the oil chambers F. The air bubbles up through the oil chambers and then passes into the carburetor chamber whence it is drawn through the conduits H and forced by the blowers into the delivery pipe I which leads to the furnaces (not shown). It is obvious of course that there is no tendency to force combustible explosive gas out of the carburetor, a leak in which permits the entrance ot' air, but not the exit of explosive gas. This feature is of course of great importance It will also be seen that the apparatus is simple in construction, easily put together and arranged in operation, and easily extended to any desired degree by simply increasing the length of the carburetor chamber and the number of oil chambers situated within it.

Where it is desired to force air, not impregnated with oil, into the delivery pipe the valves J are closed and the valves L opened; the blowers then draw the air through the pipes K and force it into the delivery pipe. It is also apparent that by having two or more conduits II each provided with a blower, an injury necessitating the stopping of one blower will not throw the carburetor entirely out of operation, and also the quality of the gas can be regulated, it being evident that it air is caused to pass through the length of the carburetor and the oil impregnated charcoal with which it is filled, it will become more highly impregnated with oil and so furnish a richer gas, than if it pass a short distance as from a set of pipes to the conduit nearest thereto, therefore, if one (of two) blower is shut 0E, the one remaining in action will draw air from all of the pipes and the resulting gas forced into the main or delivery pipeI will be richer than where each blower draws its supply of air from the pipes nearest them. The valves l? are provided to be used only when the blower in front ot which they are situated is out of operation.

Having now described my invention, what Iclaim as new, and desire to secureby Letters Patent, is-

1. The combination with a carburetor having air admission pipes leading into it from the air, of a delivery pipe I, two conduits leadingtroin different parts of the carburetor to the delivery pipe I,a blower situated 1n each conduit, each blower acting independently of the other to draw air through the carburetor and force it into the delivery pipe and a valve in each conduit whereby one of said conduits can be closed, all substantially as specified, and so that the quality of the gas can be regulated by operating the valves.

2. The combination with a carburetor having air admission pipes leading into it of a delivery pipe, a conduit or conduits connecting the carburetor and delivery pipe, a blower situated in said conduit, a valve for closing said conduit situated between said blower and the carburetor, and an air admission valve situated between said last mentioned valve and the blower, all substantially as specified.

3. A carburetor having air admission pipes leading into it in combination with a delivery pipe, a conduit or conduits leading from the carburetors to the delivery pipe, blowers situated in each conduit, valves for closing said conduits situated between the blowers and carburetor, air admission valves situated in each conduit between the above mentioned valves and the blowers and valves for closing the conduits situated between the blowers and the delivery pipe, substantially as specified.

4. The combination with the carburetor chamber A having oil chambers F situated therein, of air pipes G2 arranged in groups with their lower ends in the oil chambers and their upper ends extending outside the carburetor, a delivery pipe, a conduit or conduits leading from the carburetor to the delivery pipe, a blower or blowers arranged in said conduits to suck air through the carburetor and force it into the delivery pipe, and gas burners Q arranged beneath the oil chambers to heat the oil when necessary.

5. The combination with the carburetor chamber A, having the oil chamber F situated therein, lof air pipes G2 arranged in groups with their lower ends in the oil chambers and their upper ends extending through the carburetor chamber, a shield arranged to keep solid particles out of the oil chamber while permitting the passage of gas, and a blower arranged to suck air through the carburetor.
